UNITED STATES Application led September 3, 1925.

To all 207mm it may concern.'

Be it known that. I, RAY L. CARTER, a citizen ofthe United States, residing at Phoenix, in the county of Oswego and State of New York, have invented certain new and useful Improvements in Shapers, of which the following is a specification.

This invention relates to improvements in Shapers, designed for use by wood-workers of various classes, and has for its object to provide a light, easily portable device of the class, adapted for rounding corners, cutting beads, as well as various moulding designs, by the use of suitable interchangeable tools; the said tools being driven by a highspeed electric motor, which is adj ustably mounted upon a novel support; the said support being arranged to be guided manually, and being provided with adjustable stops or guards, by which the machine may be nianeuvered over the work, for accurately tracing intricate patterns, and the like. A further object is to provide a plane base, which is equipped with novel and simple means for readily and quickly mounting the operating parts, and whereby the shaping mechanism may be set and held at different angles relatively to said base, and also to a surface or margin of the work. And a further object is to provide a detachable cap or head which is pivotally supported by the base and directly and adjustably supports the Shaper, the said Shaper being detachable from the head and adapted to be employed for performing shaping work not readily accessible when the base and head are attached to the motor casing.

This invention relates particularly to im provements in the shaper shown and described in my U. S. Patent No. 1,433,497, dated September 26, 1922.

The various features and parts of the invention will be understood from the detailed description which follows, and by reference to the accompanying drawings, in which- Figure l is a broken side elevation of the complete device; showing the tool in the act of cutting a moulding pattern. Fig. 2 is a top-plan view of the same. Fig. 3 is an elevational view of the encased motor, and a sectional view of the head.

In the drawings, 2 represents an electric motor, having an armature shaft 2. The motor may be supplied with current in the usual manner, as by wires 2a-2lh The motor is preferably completely enclosed by a cylindrical casing' 3, which lis externally threaded at 3, k"for adjustablv mounting the motor, in any suitable holderI or support. The ends of the casingare respectively closed, by conical caps 3 and 3l. both of which are provided with openings for the entrance and exhaust of the air. by which the motor is cooled. The armature shaft 2 preferably extends beyond the apex of the cap 3", its free end being threaded for receiving a nut 2c, by which a tool. as 4, may be rigidly but detachably secured to the shaft. The device thus far described, comprises a complete shaper, which may be supported and guided by the hand of the operator, like the shaper referred to in my former patent.

In order to extend the use of my Shaper, to classes of shaping work embracing intricate and precise patterns of mouldings. and the like, that require more reliable and positive means for supporting and guiding the machine during the performance of its work, I have found it desirable to provide a novel. convenient aud light support, which preferably comprises a plane base, as 5, upon which the motor and related operating parts may be pivoted, so as to enable work to be done at different angles; the said base being fitted with handles, as GMG, by which the operator may propel and guide the shaper over the work, as A. The base 5 preferably tapers from its rear towards its forward end, the latter being made narrow in order to expose more or less of the work to be acted upon by the tool 4, and this reduced portion of the base is provided with a relatively large circular opening 5', through which the tool 4 projects. The tool shown in Fig. 1 is arranged to cut close to the bottom plane of the base, as for example, when executing the design of the common thumb moulding, A. When the shaper is mounted on the base 5, a spacing collar 4 is usually placed on the shaft 2', betwpen the cap 3b and the base of the tool. According to the showing in Fig. 1, the machine is guided by similar gage members 7, preferably disposed beneath the base, and which are adjustable in split arms of a bracket 7*, the latter being slotted, as

at 7*,to receive guide-pins 7c and also a thumb-screw 7 d, which may be threaded into 5, or other support.

preferred embodiment of the device, that the `ple Shaper of my former patent, may be the base (see Figs. 2 and 4), for holding the gage in the adjusted positions.

ywork and is employed asa guide, when the.

Shaper is operated by hand, Without the base It is desirable, in the guide surface of the cap 3b be free from pro- Vjections or obstructions that might interfere withthe handling of the Shaper and the performance of its work. To this end, in order to suitably mount the Shaper upon the base 5, I provide an enlarged detachable conical cap or head 8, into which the cone 3b and the adjacent portion of the casing 3 may be inserted, as shown in Figs. l, 2 and '4. For this purpose, the expanded end of "the head 8 is formed with an integral cylindrical internally threaded portion 8', by

'f means of whichthe motor casing 3 may be screwed into-and adjusted axially Vrelatively The reduced end of the head is' flattened, as at 8a, and is provided with a concentric opening 8b, through which the tool V4 and the shaft 2" project sufficiently to enable the tool to be operatively positioned, as shown in Figs. l and.y Adjacent the opening 8b, the head 8 is provided with oppositely facing trunnions 8c, which are jour- 'naled in bearings 8d, the latter being mount- 'ed rigidly upon the top face of the base 5,

asbest seen in Figs. 1 and 4. These trunnions constitute the aXis around which the lshaper and head rotate when said parts are swung towards ror away from the base. At

I ythe corresponding sides of the annular shaped slots 9 of the brackets 9, and thence Aflange 8', is formed bosses 8e, havingthreaded sockets which cooperate with slotted brackets 9 and set-screws 10, for adjustably mounting the Shaper and head upon the base 5. The threaded portion of the set-screws 10 passloosely through corresponding arcenter the sockets of the bosses 8B. The slots 9 are Varanged to allow the Shaper tobe f swung,"as from the incline positiony shown "by the full-lines, to the vertical position 'shown by 'the'dotted lines in Fig. l, for

Y l, enabling the tool 4to perform various kinds 'ofwork at different angles. YIn order'to. incline the Shaper and at the same time provide 'a suitable-seat for the head8, for

preventing rocking or vibrating -'of the "shaper vdue yto the high-speed of the motor,

thebase 5,isforrned, in the line of its longijtudina'l axis,7w1th a tapering trough or seat 5t, which isarranged to provide Va'ulongitudinal slot 5b,by means ofwhich the ineline surface of the head 8 is disposed'in the same planefas the bottom of the base, in

`contactfwith the work A, and serves as the trefguide for the mounted Shaper, the same x Y The cap 3b r -V is formed with a 45o vtaper whose external as the cone 3b, when the Shaper is' ldismounted, as explained. The brackets 9 eX- y tend rearwardly at the opposite sides of the Shaper, and are secured to the base by screws 9a. lhen operating the mechanically supported Shaper, shown in Figs. l and 2, the combined device is preferably propelled by the operator in the direction of the arrow in F ig.'2.
